After his last attempt to take the Crystal Kingdom, King Sombra sank into the abyss. In the total darkness of this place, he saw his life pass by, starting at the end.
He saw his actions to take back his kingdom which made him angry and then soon enough, he saw another him, in his past. This time in his life was hazy for him and he tried to remember this time better. He saw himself with normal, bright green eyes. He saw himself ruling his kingdom where instead of his people being afraid of him, they admired him.
A feeling of guilt rises in him until he sees him and Princess Celestia talking in a secret garden. His lover he had after… after his wife who disappeared a few weeks before, which had taken him to doubt… Then he understood quite quickly that it was his vision of things that had scared his wife away, who gently plunged him into darkness to become this monster. He needed to make amends for his actions to the current ruler of his Kingdom.
Out of this abyss by his own strength, Sombra headed tired, because he had to draw all his strength to get out of there, but trying to keep his head. Just entering the city, many ponies remain frozen in fear but do not flee seeing Sombra's head proud, but above all remorseful. Arriving in the throne room, he saw Princess Cadence and Prince Shining Armor on her throne, it annoyed him but he didn't want to confront them but ask for their forgiveness. Which he did by prostrating himself in them. Which confused them.
The first part of a little project I have in mind, about the Ryoku Verse with antagonist of the show. This will be articulated in 3 steps: -the first part is the excuse, you will see the antagonist return to the character or characters who hurt him the most to apologize for their act. -the second part is acceptance, where the character agrees to forgive the antagonist. -the third and final part is the afterlife, where the antagonist takes on a new life.
Have a nice day! And don't forget to watch me for more!
